Windows 8.1 - \windows\system32\winload.efi missing or corrupt Code: 0cx000000f

I have had my Lenovo IdeaPad U330 Touch 4th Gen i5 for 5 months now, and last week, lots of blue screen errors started appearing. Here is a list of the BSOD Errors I had DURING ONE DAY:
BAD_POOL_HEADER
PAGE_FAULT_IN_NON_PAGED_AREA
MEMORY_MANAGEMENT
KERNEL_SECURITY_CHECK_FAILURE
PFN_FILE_CORRUPT
BAD_POOL CALLER
ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY
Anyway, It worked fine this morning, but after I came back from lunch, It told me that my computer needed to be repaired, because the file \windows\system32\winload.efi was either missing or contained errors. I have 3 options on this screen which are:
"Press Enter to try again" - which does nothing
"Press F8 for Startup Settings" - which does nothing
"Press Esc for UEFI Firmware Settings" - which works and takes me to the "InsydeH2O Setup Utility"
What do I do to get my laptop working again??

Hi,
How about your problem now? According to your description, the only way except reinstall OS to fix your problem was create a system repair disc, USB drive is OK. Then connect to your computer to fix this problem.

Error code: 0xc0000001 file: \windows\system32\winload.efi missing or contains errors

I have a new 2 month old(Aug 2014) hp eliteone 800 all in one computer running win 8.1 64bit. i have two 1 tb hard drives raid configuration. left computer on for an afternoon and when I came back it was off mysteriously. tried to turn on and it
attempted to repair and was never able to repair. hp sent a new windows 8 software to install, they said os was corrupt. installed three times now i get error code: 0xc0000001 file: \windows\system32\winload.efi missing or contains errors. hp said installation
disc probably corrupt and sent me another. installed twice with same result, error code: 0xc0000001 file: \windows\system32\winload.efi missing or contains errors. This began after the computer was just one month old and after i had placed 300-400
gb of my personal data from other computers on it. I need all of these files so can't just recover/delete all of the files on the computer, although i have read that that may be my only solution? If i do recover will the files still be on the second hard drive??
can you help with this problem?? thanks.

Hi Richard,
Did you try to repair or reinstall the system when you insert the new media?
Have you tried to carry out a system recovery, which will restore your system back to factory defaults and how was the result?
In addition, I suggest you use the new installation media to do a clean install(full format the old system).

Error: 0xc0000001 windows/system32/winload.efi missing or ..

i have msi ge60 0nd series leptop and recently i want to recovery my system and go back factory settings but end up this error and i can' t recover. Need your help.

The error code: 0xc0000001 indicates that there might be some issues with the booting device or some booting files are corrupted. It might also happen if some problem happens with the boot sector of the computer. I would suggest you to un-plug all external
devices, except the keyboard and mouse, then try to boot the computer.
If issue persists, I would suggest you to perform Automatic repair and check if it helps.
1. Hold power button to shut down the system.
2. Press power button to start system.
3. Repeat the steps multiple times (twice or thrice until you see the recovery page).
4. After that, select "advanced repair option" in Recovery page
5. Select "Troubleshoot" in Choose an option page.
6. Select "Advanced options" in Troubleshoot page.
7. Now click on “Automatic Repair” and follow the on-screen instructions.

I have Toshiba Serial #XXXXXXXXX, model P75-A7200
Bought it brandnew at best buy almost a year ago. I did not make any recovery disc's or flash drive.
It is getting slow and someother minor issues while on internet, so I want to do a Full Reset to facory settings. I have tried the Refresh option and the Reset option. Both come back with error message ;oxc0000001, missing file: Windows\system32\winload.efi
So how do I fix this since I didnt make a recovery or start up discs? I can reboot the computer just fine, I just cant do a computer reset.
I am running Windows 8.1, came installed with windows 8, I upgrade to 8.1 shortly after I bought it.

Be sure to follow these instructions when you upgrade to Windows 8.1.

Satellite A60 crashes and reboot cycle - system32\DRIVERS\Ntfs missing or corrupt

I have a Toshiba Satellite A60 which has recently developed a serious problem and is currently stuck in a crash reboot cycle. It began with the message "system32\DRIVERS\Ntfs missing or corrupt", I have read about this problem on message boards but still am unable to find a fix.
Currently on start up various error messages are displayed stating a driver is missing or corrupt, the Toshiba start up page has vertical lines of missing data and on the few occasions it will fully boot after a short period of time vertical lines appear through the display and it crashes.
I have tried a number of fixes:
* Re installed windows XP pro (formatting the hard drive and renewing the partitions)
* Updating the bios from the toshiba site to version 1.90 (I believe the update also flashes the bios, though would need this confirming?)
* Swapping the hard drive with another laptop, still will not boot and HD works fine in the other laptop, ruling out the missing or corrupt files posibility.
I realise this could be a problem with the RAM and believe the laptop has 512 fixed to the motherboard, inaccesible without stripping down, but am not sure how to determine if RAM is the problem. Whilst trying these fixes I am getting problems with booting from the CD drive and can only get the drive to spin up and recognise the CD about 1 in 10 times.
Could anyone suggest a remedy or fix I may try? or suggest how they fixed a similar problem. Many thanks

You description ssounds not very good ;(
The hardware malfunction seems to be responsible for the vertical lines on the screen
If the vertical lines appear also an external display the board could be wrong.
Youre right, I have googled and it seems the Sat A60 supports an internal memory.
As far as I know such memory cannot be removed and only a electronics technician could solve such internal memory problem.
But are you sure that the internal memory is corrupt. The unit supports only 256MB of internal memory and other modules are removable
So you could try to replace it

My laptop A300D toshiba satellite

Hi
You mean you are not able to recover the notebook using the HDD recovery procedure?
You can start the HDD procedure pressing F8, choosing option Repair my Computer.
Then a new window should appear and there you could choose a new option called Toshiba HDD recovery.
If this is not possible then I believe that you have no other choice as reinstall the OS using an installation disk (Microsoft or Toshiba).
If you dont have such disk then you order it from this website:

Windows cannot start due to file is missing or corrupt Windows/system32/config/system

How do I recover system file from recovery disc ?

Hi,
You can get your missing file from an original windows installation disk.
To replace it you'll need a bootable CD or DVD to start your computer then put the file system (note that there is no extension) in Windows/system32/config/

Windows 8.1 Freezing and Refresh Failed - winload.efi error 0xc0000001

Hey, everybody. I'm new to these forums so I'm sorry if I do anything wrong, and sorry for the long post.
I own a three-month-old Toshiba Satellite S50D-A that came with Windows 8 installed and ran perfectly. I was eventually asked to upgrade to Windows 8.1, and assuming it was a minor update, I immediately accepted.
Unfortunately, ever since "upgrading" to Windows 8.1, my computer has suffered some severe performance issues. Browsing the internet has become slower, games run poorly, and worst of all, my computer will randomly freeze constantly. I am still
able to move the mouse around but clicking does nothing or sometimes has a very delayed response. The computer usually resumes after a few minutes, but sometimes it suddenly resets on its own. This has become increasingly frustrating, especially when I am
in class (I am a university student) and trying to take notes when the computer freezes and sometimes resets, losing my notes.
Researching on the internet has revealed that this is not an uncommon problem with Windows 8.1, but the solutions presented online have failed to solve my problems. I've upgraded every driver on my computer which I thought was the issue but the problem has
persisted.
A couple of days ago, I left my computer for a few minutes and returned to find it had shut down and refused to turn back on. I was eventually able to restart the computer after contacting Toshiba and learning there was a reset hole I could poke a pin into,
but that episode convinced me to give up on fixing the issue and to simply return my computer to factory defaults.
If anybody has any solutions to the freeezing issue and other problems with Windows 8.1, that would be preferable, but otherwise, this brings me to my new problem. I stumbled upon Windows Refresh, the ability to return to default system settings without
losing my files. This sounded perfect as I am willing to reinstall all of my programs if it means having a properly functioning computer again. However, upon attempting the Refresh, I was presented with a blue screen that read:
RECOVERY
The Application or operating system couldn't be loaded because a required file is missing or contains errors.
File: \windows\system32\winload.efi
Error code: 0x0000001
It proceeds to tell me that I can use recovery tools to repair my computer, which brings me to my next trouble... I did not create recovery media when I still had Windows 8. I plan to go out and buy a 16gb usb stick tomorrow and create one but I'm not sure
if the Windows 8.1 recovery media will work or not.
Long story short, my computer has suffered constant freezing since updating to Windows 8.1, and my attempts to use the Refresh feature have failed due to error code 0x0000001. If anybody has a solution to any of these problems, your help would be extremely
appreciated. As a full-time student, these technology troubles have become extremely infuriating.
Thank you!

Re: EQuium A100-147, wont start, \windows\system32\config\system -missing-

This laptop Equium A100-147started not connecting to internet normally, but would in safe mode.
So after trying virus scans-nothing.
System restore-nothing. I decided to put in the recovery disc and reinstall windows media.
I changed boot sequence to install it, changed boot sequence back to original.
It has reinstalled but will not go by the Windows Screen, A message has come up \windows\system32\config\system -missing or corrupt.
I cannot even see a way of doing a repair with this recovery disc??
Any help would be appreciated
thank you in advance.

That error means the Registry is corrupted.
The registry is made up from the following files:
c:\windows\system32\config\system
c:\windows\system32\config\software
c:\windows\system32\config\sam
c:\windows\system32\config\security
c:\windows\system32\config\default
You can restore these Registry files from the hidden System Restore folder on C: Drive.

Z500 One Key Recovery Error Missing winload.efi

Hi, I want to format my laptop or make a recovery using one key recovery..after setup on desktop..it load recovery and start the recovery..during setup..it show error and cannot proceed the setup.Later it show error winload.efi missing error code 0xc000000f window couldn't load It give 3 suggestion either try again by press enterF8 for startup setting and esc for UEFI firmware setting All this cannot use except esc and it bring to bios..How can I fix the error and make a recovery again I need to use this laptop urgent

You need to create a recovery disk to fix the boot files. Google how. You would most likely need an empty usb and another windows 8 computer.

Flex 15D errored within an hour of purchase with winload.efi

I unboxed my new Flex 15D an hour ago, very pleased with it, until it rebooted to install windows 8.1 updates.
When it rebooted I ended up at a blue screen saying that the file \windows\system32\winload.efi is missing.
Enter just loops back to the error, F8 flashes the screen and takes me back to the error.
Can anyone help?
Solved!
Go to Solution.

I would do a few things.
1. Go into the bios and enable legacy mode + disable safe boot
2. If that fails, use a windows 8.1 DVD image to "repair startup" (part of the advance options, before installation proceeds).
3. If that fails, then use the OKR system and try to update to Windows 8.1 again, before you load your personal files/programs. Since you got 1 hour run-time on it, I doubt you have much on the laptop. Hence, this might be your best and quickest option.
4. Or you can wait for a Lenovo Support Specialist to respond. lmao ,,,, They might have something better than the above lol.

Winload.efi

Please upload "winload.efi" for L855-S5366. This is loacated in C:/windows/system32. My laptop after booting says, computer needs to be repaired and a file ie C:/windows/system32/winload.efi is missing or corrupted. I dont have recovery media and not in position to get it from Toshiba.
Thanks in advance

Tried to look for that file with the link given by you but wont find... please guide how to download that file.
Forget about that file. It's a red herring.
my laptop boots with Toshiba logo and after that it gives that error page.
So Windows does not start? You neglected to tell us that.
This all happened when I tried to partition my C drive with Easeus partition master. ... Am newbie
Now I'm beginning to understand. You fooled around with a partition manager - in spite of the fact that you're a newbie.
Your best bet is to restore the hard disk to its original out-of-the-box contents using Toshiba recovery media. See the section Recovering the Internal Storage Drive, which begins on p. 54 of the User's Guide.

I take it you did not create recovery media. Why do you say you are not in position to obtain it from Toshiba?

Can't do clean install of Win 8.1 missing or corrupted winload.exe

I have an existing installation of Windows 7 Ultimate. It boots cleanly and works without errors. I'm doing a clean install of Windows 8.1 from DVD or flash drive (I've got both, both created from the downloaded ISO) to make it dual boot. I
get the error message "cannot install Windows 8.1, Windows\system32\boot\winload.exe is missing or corrupt." Both install media give the same result.
I don't understand where the winload file is supposed to be. It does not appear on the install media, and it can't have corrupted the DVD, and surely it's not using the Win7 partition, so what should I fix?
I see bunch of similar questions in various fora, but none of the answers seem to apply; to me, this smells like an unresolved issue with the Installer.
I'm dead in the water. Please help.

Hi SHCA,
What is your current situation?
Please share us the whole error message for better support.
Please check if the the ISO file is reliable as S.Sengupta mentioned.
As we have the error message about winload is missing or corrupted, we need to check if it's still exist in C:\Windows\System32\winload.exe.
Best regards,

<Windows Root>\system32\ntoskrnl.exe missing or corrupt.
Could any one help out...

Well, that is an odd error you are getting with the latest GPIB driver, but it is perhaps most closely linked to the fact that Windows Servers aren't officially supported OS'. We do know of customers that had Windows Server 2000 where the drivers for a Windows 2000 PC worked well on the server, but once again the Server is technically not a supported OS. Anyhow, the latest driver for XP should probably work for the Windows Server 2003, however it has not been tested by NI.
To clarify, every single response from your GPIB device included "? At" at the beginning? Does that include testing in MAX or LabVIEW or is it just with IBIC?
